Engine oil lines.

I think you're overcomplicating this. Flare the existing metal lines and run fresh metal lines or AN call it a day.

I wouldn't remove a cooler, nice to have such a thing.

That’s where I’m at. Plus it give me an excuse to buy pretty stainless hoses

As for your flexplate cover,a 4x4 cover is cast and has bosses for braces to attach to. Your missing the braces also. At this point a 2wd cover is better than nothing,until you find braces and a 4wd cover. I actually ran with no cover in the past,I ran over a basketball I didn't see and wound it up in the flex plate,yes,something is better than nothing
